I would never go with tickets over 40-50 Euros. And that is stretching it. It means 2-3 days of work, if I can get a job. Why not play bigger venues or more concerts? Roger Waters did it and despite the second time around in Athens, of "The Wall" the stadium was 1/3 full only, he didn't cancel. I know Pink Floyd fans are countless and everybody wants a ticket, but pricing desire so high ruins it for me. In the end only a few that can afford it, get to see their favorite musicians.
